Subject: [PATCH 109/112] kpatch-build: ignore changes in .comment section

.comment section contains compiler version number of compiler(s) used to
generate the object file. With LTO, it is possible that cross file inlining
add/remove items to/from the .comment section. Ignore any changes in the
section in CDO.
